// Getting the style value uses the computed style for the node, so the value

// will be a calculated value, not just the immediate node.style value.
|
|
// Also when getting values, use specific style names,
|
|
// like "borderBottomWidth" instead of "border" since compound values like
|
|
// "border" are not necessarily reflected as expected.
|
|
// If you want to get node dimensions, use dojo.marginBox() or
|
|
// dojo.contentBox().
|
|
// node:
|
|
// id or reference to node to get/set style for
|
|
// style:
|
|
// the style property to set in DOM-accessor format
|
|
// ("borderWidth", not "border-width") or an object with key/value
|
|
// pairs suitable for setting each property.
|
|
// value:
|
|
// If passed, sets value on the node for style, handling
|
|
// cross-browser concerns. When setting a pixel value,
|
|
// be sure to include "px" in the value. For instance, top: "200px".
|
|
// Otherwise, in some cases, some browsers will not apply the style.
|
|
// example:
|
|
// Passing only an ID or node returns the computed style object of
|
|
// the node:
|
|
// | dojo.style("thinger");
|
|
// example:
|
|
// Passing a node and a style property returns the current
|
|
// normalized, computed value for that property:
|
|
// | dojo.style("thinger", "opacity"); // 1 by default
|
|
//
|
|
// example:
|
|
// Passing a node, a style property, and a value changes the
|
|
// current display of the node and returns the new computed value
|
|
// | dojo.style("thinger", "opacity", 0.5); // == 0.5
|
|
//
|
|
// example:
|
|
// Passing a node, an object-style style property sets each of the values in turn and returns the computed style object of the node:
|
|
// | dojo.style("thinger", {
|
|
// | "opacity": 0.5,
|
|
// | "border": "3px solid black",
|
|
// | "height": "300px"
|
|
// | });
|
|
//
|
|
// example:
|
|
// When the CSS style property is hyphenated, the JavaScript property is camelCased.
|
|
// font-size becomes fontSize, and so on.
|
|
// | dojo.style("thinger",{
|
|
// | fontSize:"14pt",
|
|
// | letterSpacing:"1.2em"
|
|
// | });
|
|
//
|
|
// example:
|
|
// dojo.NodeList implements .style() using the same syntax, omitting the "node" parameter, calling
|
|
// dojo.style() on every element of the list. See: dojo.query and dojo.NodeList
|
|
// | dojo.query(".someClassName").style("visibility","hidden");
|
|
// | // or
|
|
// | dojo.query("#baz > div").style({
